Geothermal energy Geothermal energy is a renewable energy and can be obtained by tapping into The heat of the earth's hydrothermal sites. The water that seeps under the earth crust turn into steam and it can be used to Run turbines and created electricity.

Three typical methods for utilizing it The first method is that the steam is used directly to drive a turbine. The second is that hot water is depressurized into steam which is then used to drive a turbine. The third method is that the heated water passes through a liquid that has a lower boiling point,this causes the secondary liquid to vaporize.

The pro and con of geothermal energy Pro Is a clean energy Is a reliable source of energy. There are no wastage or products harmful like the waste of nuclear energy Con The cost to access to the geothermal sites are expensive. There are few accessible geothermal sites Is difficult to utilized the energy on a large-scale basis
